FTO and gestational diabetes: The FTO gene AA genotype was associated with an increased risk of GDM more than the TT/AT genotype in co-dominant, dominant, and recessive models (dominant: AT + AA vs. TT-wild, 63.1% vs. 49.7%, OR = 1.73, 95% CI [1.12–2.74], p = 0.018, and recessive: AA vs. AT + TT, 24.4 vs. 12.4%, OR = 2.27, 95% CI [1.23–4.19], p = 0.007) (Table 3).
